BooY-BoLsTER FOR RAlLwAY-CARS.

SPECIFICATION forming part of Lettersv Patent N o. 734,372, dated July 21, 1903.

Application filed November 11i, 1902. Serial. No. 130,908. (No model.)l

To a/ZZ whom t may con/cern): l

Be it known that I, JOHN W. SEAVER, a citizen of the United States, and arresident of Cleveland, Ohio,.have invented certain Improvements in Body-Bolsters for Railway 2. Fig. 4 is a transverse section on the line' c c, Fig. 2. Fig. 5 is a sectional planon theV line d d, Fig. 2; and Fig. 6 is a View illustrating a modification of the invention.

1 l represent the center sills with which v the bottom of a metallic railway-car is usually provided, these -sills in the present instance consisting of channels having vertical webs and horizontal top and bottom flanges, although they may be otherwise shaped, if desired.

The bolster comprises the opposite members 2, which are of similar form and project laterally from the sills l, these members consistingof castings of steel or malleable iron and having inner Webs 3, which are riveted to the sills 1, as shown in Fig. 2, the outer ends of the castings being riveted to the side sills la. The castings 2 are also secured to the sills l by means of a web-plate 4, which extends from one casting 2 to the other across the tops of the sills and is also extended longitudinally beyond the castings in its central portion. Those portions of the webplate 4 which overlap the castings 2 are riveted thereto, as indicated at 5,and the longitudinally-extending centralfpo'rtion of the .web-pl-ate is secured to the vertical webs of the sills by means of a bracket-plate 6, suitably riveted to the Webs of said sills and to the web-plate, as shown in Figs. l and 2. By this means a strong and rigid connection of the bolster-castings 2`and the sills l is effected,and the desired stiffness and strength of the bolster are insured.

The bolster has seats 9 for the support o the longitudinal timber sills sometimes employed in addition to the center sills l, these seats, as Well as the top flanges of the bolster and the web-plate 6, being perforated for the recept-ion of the bolts whereby said supplementary sills are secured inl place. (See Fig. 4.)

The sills l have secured to them the usual central bearing 7 for engagementwith a cen.- ter bearing on the truck-bolster, and the bottom web of the bolster is extended, as shown at 8 in Figs. 2 and 3, so as to constitute the side bearings of the bolster. The web-plate 4 may be riveted to the upper flanges of the plate 6, if desired, as shown in Fig. 6.

Having thus described my invention, I claim and desire to secure by Letters Patent- A body-bolster for railway-cars comprising oppositemembers secured to the center sills of the car-frame, a web-plate secnredto the upper portionsof said bolster members and having a longitudinally-projecting portion, and a bracket-plate whereby said longitudinally-projectingportion of the web-plate is secured to the sills, substantially as specified.

In testimony whereof I have signed my two subscribing witnesses.
